Ok as I'm not going to get a straight answer I will say that I am looking for a camera system which will equal or better my contax system. But it must have some attributes which I require. Specifically it must me quiet and very portable. I'm specifically not looking for a medium format or larger format camera. Therefore it's going to be 35mm and either an slr (which I don't think I will get anything better than my contax system in terms of lens quality) or a range finder. So if its a range finder, then for the expense of going that route, am I going to see an improvement in image quality for short to 85mm lenses?
I know there will be other benefits for people photography in low light and bokeh, but will there be benefits when I'm using it for landscape photography? That might make the difference between me staying with my contax system or not? There is plenty of fast glass available for the contax for low light photography ( some of which I already have ). So back to my original question. Will I see a difference with a rangefinder on a tripod when shooting expansive landscapes.
